Evaluating the dynamic response of structures due to arbitrary base or support motion can generally be facilitated by numerical integration methods. The response of structures to base excitation is the most important consideration in earthquake engineering. Consider the one story shear frame shown in Fig. 1. The structure experiences any arbitrary ground displacements or acceleration i "s (1). It is assumed that the shear frame is attached to a rigid base that moves with the ground. In analyzing the structural response there are several components of motion that must be considered; specifically ui. - Ut M K/2 Ground Rigid base Ug Figure 1:one story shear frame
